Bought a NOS cruise control kit...but...

I recently picked this up on Fleabay recently. Well-intentioned seller, but it turns out it might be missing some pieces AND may not fit my car. It is part number 1188389-9, which turns out to be the cruise control installation kit (US), B21LH, 1982. I have a '93.

So the threshold question is, can this be made to fit my car - a '93 - and if so, how? Or should I just flip it back on Ebay? (it has a cool OG sticker too!) I understand the later ones had a computer module too, which this kit never had.

The other question is - what parts are missing?

Looks like the following are missing:

"servocylinder" - Vacuum pump with mounting bracket, I think (the '82 version looks dissimilar from later ones I tend to see come up used
"deceleration sender" - IDK what this is or what the "newer" equivalent is called; diagram is bad, but seems to be in front of "servocylinder"
"valves"

I appreciate any guidance. As a thank you, please steal this meme I made last night.

The '93 system is very different, it was used years '90-'93. It seems to me that all. '90+ 240's are wired for cruise, and all '90's in the USA came standard with cruise, so I'd sell the kit you got and find a '90 that is being parted out.
 
We have some incomplete cruise control kits including 2 of the same part number as yours. We were trying to sell everything together but there's been no interest. I'm not sure we have the pieces you're missing since the pic isn't working and we're not back from our trip to see the eclipse yet. I'll look when we get back this weekend. The kit will be worth more if it's complete.

FYI, the deceleration sender is a mercury switch. If the car decelerates too quickly it will break the contact and turn off the cruise control. I assume it's there in case the driver falls asleep and the car hits something.

You're missing the 2 most important parts - the big vacuum/servo motor and the electronics control box (the upper left thing is just an empty vacuum can - IDK if those were turbo-only or std)

The Gen III Volvo 240 cruise control (1989-1993) is what you need. It is not worth the effort to retrofit the older type in your 1993. The Gen I system you purchased (1980-1985) needs a pickup which is mounted on the back of the mechanical speedometer/odometer. in 1986 the 240s have an entirely different electronic-based speedo/odometer set up. Your 1993 already includes the connector for the brain/ECU box as part of the factory wiring harness.

After picking up my 1993 240, I retrofitted a cruise control system into the car after pulling the required parts from a donor in the junkyard. It is not a hard operation, but access is a bit restricted because of the steering column. Installing the CC system: https://www.flickr.com/photos/68144590@N00/albums/72157650461834275

The interior parts for the Gen III CC set up:
(Except for the turn signal stalk with the cc controls and vacuum line to the pump, my car is a manual so I need two pedal switches)

The other required part is the vacuum pump mounted in the engine compartment.

Agreed 100%, you're missing the "brain" and the "muscles" of the whole enchilada. The servo for the older system is under the hood near the right shock tower, and relies on a separate cable parallel to the throttle cable. I've never owned a newer system, but I believe it uses a servo in the cabin, right next to the gas pedal.

The vacuum can is for turbo cars: there's a check valve so that the CC can continue to enjoy a supply of vacuum even when the engine goes into boost.
 
I bought the older system kit from a dealer in the early '80's. I installed it in my "81 242 and it worked for many years until the controller failed. As highway traffic got more crowded I had to continually reset the speed as I caught up to slower cars. I think that for today's traffic only a radar follower type is practical.
 
single speed cruise works... if you're driving slower than most traffic.

I like it on the interstate since the wind noise in the XC gets pretty loud over 75 or so
